Denver TMAU Test Lab survey click here
click to Read more/less

USA survey for anyone who wants to improve Denver TMAU test

begun : Dec22
end : no ending for now

A trainee genetic counselor is working at the Denver TMAU test lab. Probably as part of her training. As a project she wishes feedback on any aspect of the Denver TMAU test and process. You can fill in the survey and/or email her (email address is in survey). It's meant for USA people, but perhaps others can give their view too (as we have so few opportunities).

quote from her rareconnect post

"Hello all! I wanted to make you aware of a research study being conducted to better understand the experience and needs of individuals with trimethylaminuria with a goal of being able to create improved patient and healthcare provider education materials. Any participation is completely voluntary and all responses remain confidential. Feel free to use the contact information within the link with any questions or share the survey with others with TMAU."

NEW GOVERNMENT FUNDS RECEIVED FOR TMAU THERAPEUTIC RESEARCH


NEW GOVERNMENT FUNDS RECEIVED
FOR TMAU THERAPEUTIC RESEARCH

I am very excited to announce that a group of scientists, some of whom are MEBO Research Scientific Advisors, including a world-renowned expert in the genetics and treatment of TMAU, have received a sizable UK government grant for research into a potential therapeutic treatment for TMAU, under a collaborative academic-company funded grant initiative. The selection looked at a variety of factors, including promising laboratory and clinical research, existing infrastructure, and possible advocacy efforts. Private funds will help enormously to complement the government grant and the research. Lead scientists from Trinzyme (UK) Limited ("Trinzyme") are working with MEBO Research ("MEBO") to undertake an international drive to raise
$100,000/USD
or any other currency, British Pound Sterling, Euros, etc.,
to drive this research forward and to ultimately reach clinic trials.

This is an opportunity to research a therapeutic treatment of TMAU! Of all the diseases that could have been selected— thousands of disorders to choose from — TMAU was chosen. We at MEBO, are asking the community to donate whatever they can to further the use of these grant funds, and to brainstorm and volunteer to help create fund-raising projects.


AN INTERNATIONAL CAMPAIGN

HOW TO DONATE: Donators will have the option of donating directly to Trinzyme in US Dollars, British Pound Sterling, or most other currencies. PayPal will convert your currency automatically when you make your donation.

A POTENTIAL THERAPEUTIC TREATMENT FOR TMAU, UNDER A COLLABORATIVE ACADEMIC-COMPANY FUNDED GRANT INITIATIVE
In British Pound Sterling (GBP)








Our study will test a therapy for TMAU that will reduce the amount of urinary trimethylamine excreted.

In United States Dollars (USD)





FOR TAX EXEMPT DONATIONS

If benefactors are looking for tax exemption benefits, donations can be made to the MEBO Research, Inc., 501(c)3 US Public Charity, who will forward the funds to Trinzyme. If so, please email maria.delatorre@meboresearch.org. The MEBO Research company registered in England and Wales, is in the process of registering for Charity status in order to also be able accept tax exempt grants and donations, which will then be forwarded to Trinzyme.


CrowdFunding site with Indiegogo: This site has been created by one of our scientists to help raise funds for this research! You are welcome to use this or any of the other tools to donate towards this very valuable research.


This pre-clinical findings will prepare the way for clinical studies in humans in the future.
This opportunity provided to us by the UK government is very encouraging to our scientific group and to MEBO Research in taking the first steps in this long-term research, ultimately involving clinical trials, with the aim to discover effective treatment for TMAU.


LOOKING FOR VOLUNTEER FUND RAISERS AROUND THE WORLD: This drive will be approaching private benefactors for large grants as well as asking for donations from sufferers around the world. We believe that having this strong government support will propel our efforts forward, but it is really up to all sufferers to come together and to brainstorm on how we can best raise funds for this cause. The perfect place to brainstorm for this is in MEBO Research’s Facebook page, in which posts are only seen by Friends of this MEBO Page, and not friends of friends or publicly. If you are not already a friend in this site, please feel free to send me a friend request or message me on Facebook at http://www.facebook.com/maria.delatorre.39545.

There will be much discussion about this grant in our community, especially regarding the very proactive and assertive fundraising efforts to be carried out in the following months. I hope each sufferer brainstorms and recommends ways he or she can be a part of the ideas they bring forth.


Abstract originally submitted in the MRC grant application

Trimethylaminuria (TMAU) is a disorder in which affected people suffer from severe body odour often accompanied by severe bad breath. The disorder arises because of mutations in a gene called FMO3 and not because of poor hygiene. Why do changes in the FMO3 gene cause body and breath odour? When we eat food that contains choline (which many foods do, e.g. red meat, seafood, some vegetables, soya, eggs and chocolate) then the bacteria that live in our gut cause the problem. The bacteria break choline down to produce a small molecule called trimethylamine. This chemical is the one to which the human nose is most sensitive and which is also the chemical that gives rotting fish its characteristic smell. In people with a normal FMO3 gene there is no odour problem because the FMO3 enzyme we have in our liver changes trimethylamine into a chemical that does not smell. BUT, if the FMO3 enzyme cannot do this, then the trimethylamine is not changed and is excreted in urine, sweat and breath. Social isolation, ridicule and limited employment prospects are experienced by those with TMAU, this usually means a low quality of life; high levels of depression, suicide and divorce occur in this population. Our study will test a therapy for TMAU that will reduce the amount of urinary trimethylamine excreted. Our pre-clinical findings will prepare the way for clinical studies in humans in the future. A reduction in body and breath odour will contribute greatly to an improved quality of life for those with TMAU.

Thanking everyone in advance who will be participating in this mass fund-raising opportunity, knowing that each dollar, each pound, each euro that is collected will be matched by a UK grant!

Happy Holidays 2012

...the cause of body odor produced by alcohol consumption may be based on personal trigger(s), such as choline, sulfites sensitivities, glucose in fruity drinks, and/or the alcohol itself.....

HAPPY HOLIDAYS 2012

There have been a few posts written in this blog discussing better alternatives for consuming beverages and foods while vacationing and partying, something most tend to do on this holiday season. Here are some excerpts from these posts:

  • WHITE WINE, 4oz/120g contains 6.180mg of choline and 0.180mg of betaine per serving.
  • LIGHT BEER, 12oz/360g, contains 25.416mg of choline and 25.092mg of betaine per serving.
  • REGULAR BEER, 12oz/360g, contains 34.956mg of choline and 34.992mg of betain per serving.

The cause of body odor produced by alcohol consumption may be based on personal trigger(s), such as choline, sulfites sensitivities, glucose in fruity drinks, and/or the alcohol itself. Perhaps the ideal conditions would be for all sufferers to have access to more diagnostic testing in all these areas, but since we currently do not, it all boils down to an individual trial-and-error solution.

  1. Aldehyde dehydrogenase enzyme
  2. Increased gut permeability
  3. Choline- and betaine-defined diets for use in clinical research and for the management of trimethylaminuria
  4. Sulfites and Wine
  5. The ‘fruity drinks’ and gut fermentation

Johnson & Johnson removes harmful chemicals


In an effort to control the pH of the odorous chemicals on our skin, sufferers of various types of body odor have been using acidic or pH balanced skin cleansers and lotions like Neutrogena and baby shampoo, both Johnson & Johnson products, amongst others. See multiple posts in this blog on skin cleansers.

One of the suggestions on The trimethylaminuria paper published the NIH Gene reviews site, by Drs. Phillips and Shephard, London, for a TMAU (trimethylaminuria) management protocol is the use of an acid soap/cleanser, with some containing salicylic acid, to attempt to neutralize the highly alkaline trimethylamine. However, other odorous chemicals other than TMA might not be as alkaline, or may be more acidic, and therefore, a neutral pH cleanser or lotion might be more effective.

And now J&J vows to remove formaldehyde from its products by the end of 2015.
Johnson & Johnson products offer both acidic (containing salycilic acid) and pH balanced products, which would make their products very attractive to our community. Nevertheless, environmental and consumer groups have been pressuring this company and its competitors to remove questionable chemical ingredients for them. As a result, J&J has vowed to remove certain chemicals from baby products by 2013, including well-known brands like Neutrogena, Aveeno, and Clean & Clear. And now J&J vows to remove formaldehyde from its products by the end of 2015.


Johnson & Johnson, which makes a range of personal care products like baby shampoo, acne cream and antiwrinkle lotion, announced plans Wednesday to remove a host of potentially harmful chemicals, like formaldehyde, from its line of consumer products by the end of 2015, becoming the first major consumer products company to make such a widespread commitment.

TMAU Test Results - 3rd Batch

Click on icon to see chart
THE RESULTS OF THE TMAU TEST, BATCH#3 ARE IN.

A TMAU Test Results Chart of all 86 TMAU tests with Liquid Chromatography since the commencement of this program in the Summer of 2012 has been created. By seeing where your figures fall in comparison to other sufferers who tested, you can get a better understanding of what role TMA plays in your odor condition.

NOTE: Please keep in mind that this table does not depict the figures of one individual on the same row, and consequently, the significant relationship among the TMA levels, TMAO levels, and the TMA/TMAO Ratio of any one particular individual is not noted except for those of our three volunteers noted on the chart; this was done intentionally to protect the privacy of each participant.

In an effort to facilitate understanding of how to obtain information from this chart, three volunteers have come forward and given permission for their figures to be mapped on the chart for the sake of comparison and understanding, as long as they remain anonymous. Anonymous TMAU1 is a volunteer whose results are indicative of Primary TMAU (genetic TMAU) with an above normal TMA/TMAO Ratio. Anonymous TMAU2's results are indicative of Secondary TMAU (acquired TMAU) with increased TMA. Anonymous Negative for TMAU, is a sufferer who presents with intermittent odor, and this test did not show TMAU to be the cause of his symptoms at the moment he collected his sample.

The pink cells that don't have a description of the participant's identification are all Primary TMAU. The indicator for Primary TMAU is the TMA/TMAO Ratio column. Another indicator of Primary TMAU is that the numbers are usually very low on the TMAO column. This is because an FMO3 metabolic enzyme's function is to add the oxygen (O) element to the odorous TMA, to thus renders it non-odorous. In Primary (genetic) TMAU, the FMO3 enzyme is deficient, so alot of odorous TMA stays in your blood without the oxygen element being attached to it.

In the TMA column, as in all three columns, the top numbers in red figures are the above normal range, which means that these people have high levels of TMA (odorous chemical - rotten fish odor) in their blood and coming out of their urine. Once you get to the black numbers, those persons have normal range of TMA, so they shouldn't be smelling of rotten fish. That doesn't mean that they don't smell, it does mean that it's not from the chemical, TMA, that gives off a rotten fish odor. If you scroll down to the second page, you will find your figure of 0.46/TMA, which means that you have relatively low TMA levels in your blood, and it's low even in the normal category. Could it be that you are on a very low choline diet? If not, then you don't have an overgrowth of bacteria that converts choline to TMA in your gut. If you are on a very low choline diet, then you could probably eat more choline, and still be within the normal range that does not emit rotten fish odor. In other words, your odor is of a different chemical, yet to be identified, not of TMA.

The TMAO column is the TMAO levels. TMAO is a molecule in which the FMO3 metabolic enzyme added an oxygen element to the odorous TMA to render it non-odorous. The persons who are on top of this list have a very active FMO3 metabolic enzyme, and therefore, do not have the hereditary type of TMAU (Primary TMAU). The genetic type of TMAU is caused by a deficient FMO3 metabolic enzyme that cannot handle normal loads of TMA, resulting in it staying in its odorous state without having the oxygen added to it. The TMAO level is also dependent on the amount of TMA in your body. It's impossible for the FMO3 enzyme to add an oxygen element to a non-existent TMA.

The TMA/TMAO Ratio, is what really indicates whether you could possibly have Primary TMAU. It's all about the relationship (ratio) between your TMA levels and your TMAO levels. The TMA column and the TMAO column could be very low, but the results of the Ratio column is what shows whether the FMO3 metabolic enzyme is working properly when TMA is present. For example, anonymous TMAU1 did NOT do a choline load for the test, so his TMA and TMAO are very low. Yet, his Ratio was very high - indicative of having the genetic form of TMAU. It shows a weak FMO3 enzyme activity when faced with TMA. Your result figure in this column is very low on the 2nd page.

Thank you to everyone who has participated in this and other MEBO Research Programs.

Considering which TMAU Test Program





On December 4, 2012, someone signing as Anonymous raised a question in a post comment in this blog, Three main protocols of TMAU Diet, that may very well be expressing a common concern in many sufferer's minds when faced with making a decision of where to test for TMAU. It made me think of how difficult it is to decide on which way to turn to find a diagnosis and treatment, and of all the factors that need to be considered. As a result, the following are the recommended points of interest to be considered in order for each individual to make a decision that is right for her or him according to the particular needs of each sufferer.

Although all are looking for answers, not all sufferers are looking for the same criteria when testing. Some are more concerned with cost, others with the streamlined simplicity of the test process, some with obtaining results sooner than later, and all want to obtain as many answers from one test as possible. The following are the recommended questions sufferers could consider before making a well-thought out decision:

  1. Is this a reputable lab that would provide accurate results?
  2. Will the test look for TMA (odorous chemical) levels as well as metabolized TMAO (non-odorous chemical), and the ratio between them, which is the indicator of whether one has the genetic form of trimethylaminuria (TMAU)? If the test shows all three figures, it will indicate how much odorous TMA is in the system, how well or how poorly the metabolic enzyme is working to convert TMA to the non-odorous state, and with this information, calculations can be made to determine whether the patient could have Primary (genetic) and, depending on the lab used, Secondary (acquired) trimethylaminuria (TMAU) may also be indicated on test results. See Nigel Manning's interpretation of test results.
  3. Will my insurance or National Health Service cover 100% of the test cost, or would I have to pay for it myself.
    • Insurance companies and National Health Services will only cover the cost of diagnostic tests when ordered by physicians.
    • Only research laboratories that perform the TMAU Test for research purposes are allowed to do the TMAU Test without a physician referral. However, without a physician's orders, insurance and National Health Services will not cover the cost, leaving the burden of payment solely upon the patient.
  4. Will I need to pay various times during the testing process, including making the arrangements for the return shipment on dry ice where applicable? If so, what would the total cost be from my first payment to my last shipping payment?
  5. How long will it take for me to receive my results from the moment I first pay for my test?

To some sufferers, cost is of the determining factor, while to others, obtaining faster results is the most important, and then there are sufferers whose primary concern is to streamline and simplify the testing process with most of the work being done by the provider. Since there are sufferers around the world that have different needs and preferences, there is a page in this blog listing many labs around the world, and sufferers are encouraged to email these labs to ask any and all of the above-mentioned questions about their test process.

Please note that this list was created almost two years ago, and some information may be outdated, and for this reason, sufferers are encouraged to email the labs. We ask our community of sufferers to please point out to MEBO Research at test@meboresearch.com any information that has changed, so that it may be updated on this list for others to benefit from. We hope that information on this page is of assistance to sufferers in making an informed decision.
-----------------------

THE MEBO RESEARCH TMAU TEST PROGRAM

TMAU TEST PROGRAM DEVELOPMENT:
It has been MEBO's goal to develop a seamless test method that is very user-friendly, safe, and very accurate, while keeping cost down to a bare minimum. This has been accomplished with months of testing various sample tubes under a range of temperature and pressure conditions, simulating shipping in winter and summer, and flight conditions, to ensure that TMA does not escape from the tubes under these conditions. This study was conducted using simulator instruments in the lab as well as in the field shipping samples from the lab and back on transoceanic and transcontinental flights. By comparing the results before and after shipping, and comparing them with a control group, it was determined that shipping under these conditions for no more than 2 or 3 days. In the end, a test process was designed not requiring the sufferer to ship the sample in ice, as long s shipping is done in two to three days time.

MEBO RESEARCH'S ROLE IN THE
INTERNATIONAL TMAU TEST PROGRAM:

In a coordinated effort, MEBO Research negotiated shipping rates with UPS and FedEx to ensure that shipping could be arranged to any part of the world, and especially to those countries where sufferers have never had the hope of ever being able to do this test. Another way to keep cost down was for MEBO Research to offer volunteer work in performing all the administrative work for this program, including accepting applications, sending invoices, receiving payments, creating shipping labels and Commercial Invoices for U.S. domestic and international shipments, as well as the return shipping labels and Commercial Invoices. In this manner, the cost of the test is only $150, and the only other additional cost is round trip shipping cost charged by UPS. MEBO Research ships the kit to the sufferer with easy to follow instructions, return shipping label and Pak, so that all the sufferer has to do is collect the sample, freeze it, put it in the box and Pak, and send it via UPS. No additional cost or steps in this testing process.

FOR TOTAL PRICE QUOTE:
For a round trip shipping quote, please fill out the

Requisition Form, (program discontinued 2017)
(without obligation to purchase the test).

WHAT WILL MY TEST RESULTS LOOK LIKE TO SHOW MY PHYSICIAN FOR TREATMENT:
Test results include your figures for TMA, TMAO, and TMA/TMAO Ratio levels in urine sample. The testing is done by the same method originally developed at the Cleveland Clinic. It provides Normal Reference Range for Liquid Chromatography. Comments are provided stating whether your results are indicative of Primary TMAU, Secondary TMAU, or Negative for TMAU. The following two pages of this report include an introduction to TMAU, and explanation of Primary and Secondary TMAU, and the commonly accepted 'Odor Management Protocol,' as noted in the NCBI Bookshelf, publication, 'Trimethylaminuria,' written by MEBO's Scientific Advisor, Dr. Elizabeth A Shephard (See all Dr. Shephard's posts, powerpoints, and webinar created for MEBO's blog) and Dr. Ian Phillips. This website publication is a service of the National Library of Medicine, National Institutes of Health, updated 2011. The last page of your Results Report is a list of References on publications related to TMAU that your physician might find interesting.

HOW LONG IS THE TESTING PROCESS FROM PAYMENT OF THE TEST TO RECEIVING TEST RESULTS?:

DATE: 08 December 2012
Now on : Batch #4
Samples to collect before next shipment to lab : 20
Current sample count for Batch 4 : 6
Total Program samples sent to lab since June 2012 : 87

Normally, the test process lasts 2 to 3 months, from the time the sample is sent to MEBO to the time MEBO emails your Results Report to you to show your doctor. This wait-time estimation is based on the past 6 months of testing involving 94 tests purchased. Any test trial runs done before June 2012, cannot be considered because it is not the program being offered, but rather the developmental stages of the program. We are currently working on Batch #4, and began Batch #1 in June 2012. However, if a sufferer finds a program that would give them results faster, while costing them over $100 to $150 or more than MEBO’s rate, and the sufferer believes that perhaps getting the results a few weeks earlier will make that much difference for the price, then by all means, they should go for it. Each person is the best judge of what he or she needs.
PLEASE SEE THE SIXTH MONTH REPORT, MEBO TMAU TEST PROGRAM,
NOTE: I have received 2 additional Requisition Forms and one purchase after this report was written, so it is not completely updated.

All TMAU test programs using the instruments, such as Gas Chromatography, Liquid Chromatography, Mass Spectrometry, and Nuclear Magnetic Resonance (NMR) instruments, discussed in Dr. Richard Mackay’s webinar, sponsored by RareConnect this past Sunday, December 2nd, are equally as accurate, as he pointed out in his powerpoint presentation.

MEBO has received 9 Requisition Forms and payment for 3 kits in only the first 8 days of December.
Based on what we’ve seen these past three months, it may take 8 to 12 weeks to receive your results depending on the time I receive your payment while collecting 20 samples for your batch. This month is the Christmas and New Years holiday, so people might not be purchasing kits when spending money on their holidays. Having said that, to date, MEBO has received 9 Requisition Forms and payment for 3 kits, in only the first 8 days of December. WE currently have 6 samples in the freezer, and need 14 more to complete the 4th Batch of 20 or more samples to send to the lab. Updated Batch information is found in the centerbar of this blog under the requisition Form. The more we get, the faster we ship batches to the lab, and the faster the results come back.

Ataluren receives validation of marketing approval by EMA

Ataluren, a new drug made by PTC Therapeutics, yesterday announced that it had received validation of a marketing authorization application for Ataluren by the European Medicines Agency (EMA) for the treatment of Duchenne Muscular Dystrophy  (DMD).

This seems to mean that it is at least being considered for approval which will ultimately lead to it's approval for sale by the EMA. Although in this case it is being marketed for nonsense mutations in DMD, it should in theory be of some help to people who have a nonsense mutation of any genetic disorder. Typically, nonsense mutations make up about 5-10% of cases of a genetic disorder, and with FMO3 mutations it is likely to be around this amount.

missense and nonsense mutation analogy
Nonsense mutations are a 'severe' type of mutation. In the case of FMO3, which is a 532 amino acid sequence, it means that a false stop is inserted into the 532 sequence somewhere in the sequence (rather than at the end where a stop codon should be), and the FMO3 protein does not then get properly formed.

So this is an exciting milestone announcement by PTC Therapeutics, but presumably it still has a way to go before being a drug available in Europe.

TMAU webinar with Dr Mackay, a great success

4th Webinar

Thank you to Dr Richard Mackay, FRACP, FRCPA, Clinical Biochemist at Canterbury Health Labs in Christchurch New Zealand for his informative lecture on Sunday, December 2nd, given to our community at 8:00 am on a Monday morning his time!

Dr Mackay gave us a biochemical explanation on the metabolism of trimethylamine (TMA) and trimethylamine oxide (TMAO) from the point of ingestion through the small and large intestines to the kidneys and urine. When TMAO (from fish) and choline betaine is consumed, some choline betaine is absorbed by the small intestine and goes in the portal blood to the liver. Some of the choline betaine and TMAO continue on to the large intestine and colonic bacteria converts both to TMA (odorous chemical), which also travels in the portal blood to the liver, where it is converted into TMAO (non-odorous state) by FMO3 enzymes. When there is a deficiency of FMO3 enzymes, odorous TMA goes into the main bloodstream and is excreted in the urine.

Dr. Mackay discussed...the use of instruments, such as Gas Chromatography, Liquid Chromatography, Mass Spectrometry, and Nuclear Magnetic Resonance (NMR), and how they are all equally accurate for testing TMAU.
Dr. Mackay discussed the various tools and methods used around the world to perform the TMAU Test, from describing the loads used, including fish, choline, or trimethylamine pills, to the instruments used for analysis. He explained in some detail the various methods used for testing human samples with the use of instruments, such as Gas Chromatography, Liquid Chromatography, Mass Spectrometry, and Nuclear Magnetic Resonance (NMR), and how they are all equally as accurate for testing TMAU.

An interesting point he made is that in the case of TMAU, all seafood should be avoided because it contains TMAO that is converted into TMA by colonic bacteria, other than tuna, which does not seem to contain TMAO. In addition, foods rich in choline betaine and carnatine should also be avoided because bacteria in the gut also converts these into TMA. Dr. Mackay concluded his presentation with a very interesting discussion on the genetics of TMAU.

At Dr Mackay's request, this webinar was not recorded.

Dr Mackay is the lead author of the publication, Trimethylaminuria: causes and diagnosis of a socially distressing condition.

Our thanks goes to Dr Mackay for his excellent presentation, to Rob Pleticha for hosting this webinar, and to everyone who joined in and raised interesting questions.
